IMPROVEMENT IN FLIERS FOR SPINNING MACHINERY.

Specification forming part of Letters Patent `No. 33,856, dated September 24, 1861'.

To al@ whom it may concern:

Be itv known that I, I. F. MAYNAED, a resident of Nashua, in the county of Hillsborough and State of New Hampshire, have invented and made certain new and useful Improvements in Cotton and VVoolen Machinery; and I do hereby declare that the followingis a full, clear, and eXact description of the same, reference being had to the accompanying drawings, making a partf'of this specification.

Figures l and 3 represent fliers, showing my improvements. Fig. 4 represents a portion of a iiier, showing the whirl and pedestal part in a vertical section. Fig. 5 represents an inverted view of the head and nose of my improvements. Fig. 6 represents the nose detached and in a vertical position. Fig? represents a top view of a pedestal and whirl of the ordinary kind.- Figs. 8 and 9 represent, respectively, a detachable whirl and a detachable nose formed with left-hand screwthieads and a rounded shoulder connection, as indicated by the curved line of dots.

0 The nature of my improvements consists in constructing a flier with a left-handed screw attaching whirl and also a left-handed screw attaching nose, each being formed so as to fit onto their respective parts by a rounded shoulder connection or tenon. The employment of the left-handed screw-whirl and nose connection is designed to prevent the loosening of the flier in its rapid rotary m0- tion. The spiral thread ot' the screw connection runs in an opposite direction to the rotary motion of the flier and Whirl. Hence the revolution thereof, in connection with a tension-draft of the yarn against the nose of the ther, combine to keep the parts securely together. Otherwise, were a right-handed screw connection used, the draft or( `tension of the yarn would invariably loosen the parts.

The betterto enable others to be skilledin the construction of my improvements in fliers and to understand more fully the nature, construction, and `operation thereof, the following 1s deemed a sufcient description of the same.

In Fig. 1,6m represent an ordinary-shaped whirl, b b being the neck part of `the Whirl, c2 c2 indicating the upper part of the neck. d indicates the pedestal part, into which the left-handed screw-thread e of the neck lits,

and in `.the sides of which pedestal the elbows of the arms ffff are inserted permanently by screw ends, said arms being made of suitable steel wire. r At g g is represented the Iiead of the flier, `Fixed permanently to the upper extremities of the arms. This head g g is formed with a female left-hand screwthread, into which is fitted acorrespondinglyformed left-handed male screw-nose 7L h, formed with the conical-shape bore or pas sage I I. (Indicated in Fig. l.)

In Fig. S is shown the whirl detached, formed with the left-hand screw-thread, as indicated at e e. This whirl is also bored out of the required size for the spindle to t in, as in the usual manner of employing the flier.

In Fig. 9 is represented the left-hand screw detachable nose ot the iiier, showing the screw formation J J.' This nose, as Well as the whirl, is, by means ot screw-threads, adjustable in or out, more or less, as may be required, and without tending to work out of aright-hand screw similarly employed will not remain adjusted as desired.

By a reference to Fig. 8 the'curved line of dots shows that the upper part of the neck of the Whirl is formed with a concaveV or grooved shoulder c c, `instead of a at and sharp edge surface or shoulder-tenen. This formation corresponds with the end formation of the pedestal b, (indicated in Fig. 1,)

the convex or ro-unded tenori-shape connec tion. The concave groove and convex tenon connection I also apply to the head and nose g g 71, h, Fig. l.

tached to the head g g permanently and rigidly, as shown in Fig. 3 at 7L h t' t', and consequently will not admit of adj ustability of position nor ready detachability when desired, so as to substitute different sizes of noses. Therefore my improvements present several very important advantages not found per taining to or resulting from the use of the ordinary kind of iers, as represented in Fig. 7

to spindles of cotton machinery by means of a left-hand screw-thread. Therefore such arrangement of fliers I do not claim.
